Chief of Staff

About the role

You'll own one of Buena's next revenue verticals from zero. Pick a vertical (Brokerage, Energy and metering services, Insurance, Financing, or adjacent businesses), and build it into a real business. You'll own the P&L, the strategy, the partnerships, and the product.

What you'll do

• Own the P&L for your Vertical. Revenue, margin, payback.
• Drive the product, don't request it. Define what needs to exist for your vertical to work, write the spec, work directly with PMs and engineers, and ship it.
• Roll out across all portcos. Design the rollout, measure it, and ship the playbook so it works the same way in every portco.

What you'll need

• You've started something before. A company you founded, a product you built and sold, a freelance business you scaled.
• You think commercially first. Unit economics, margin, payback, deal structure.
• You won't be a brokerage or banking expert on day one. You'll be one in 60 days because you'll outresearch and outthink everyone.
• You act fast. Reversible decisions don't get a second meeting.
• You can sell. You've personally closed deals, signed partners, or convinced people to give you money.
• You speak native-level German. Most partners, regulators, and customers operate in German.
• You work from the office in Prenzlauer Berg. This is not a remote role.

What they offer

• Up to €500 close-to-office bonus if you live within 10-20 mins walking distance.
• €110/month lunch budget, €50 fitness subsidy.
• €1,200 yearly education budget and free books.
